Member Typedef Documentation

◆ SoWWWInlineFetchURLCB

typedef void SoWWWInlineFetchURLCB(const SbString &url, void *userData, SoWWWInline *node)

This is the format for callbacks that will get URL data for us.

Once they get the data, they should call the setChildData() method.

Definition at line 74 of file SoWWWInline.h.

Member Enumeration Documentation

◆ BboxVisibility

enum SoWWWInline::BboxVisibility

BboxVisibility.

Enumerator
NEVER	Do not show bounding box.
UNTIL_LOADED	Show bounding box (if specified) until data is loaded.
ALWAYS	Show bounding box along with data.

Definition at line 131 of file SoWWWInline.h.

Constructor & Destructor Documentation

◆ SoWWWInline()

SoWWWInline::SoWWWInline ( )

Creates an inline node with default settings.

Member Function Documentation

◆ cancelURLDataRequest()

void SoWWWInline::cancelURLDataRequest ( )

inline

Cancels the active URL data fetch request.

Definition at line 210 of file SoWWWInline.h.

◆ copyChildren()

SoGroup * SoWWWInline::copyChildren ( ) const

Return a copy of the hidden children as a Group.

The children are set by the application through setChildData().

◆ getBoundingBoxColor()

static const SbColor & SoWWWInline::getBoundingBoxColor ( )

static

Queries the color of bounding boxes displayed.

◆ getBoundingBoxVisibility()

static BboxVisibility SoWWWInline::getBoundingBoxVisibility ( )

static

Queries when bounding boxes are displayed.

◆ getChildData()

SoNode * SoWWWInline::getChildData ( ) const

Gets the child data the inline should display.

◆ getClassTypeId()

static SoType SoWWWInline::getClassTypeId ( )

static

Returns the type identifier for this class.

◆ getFullURLName()

const SbString & SoWWWInline::getFullURLName ( )

Returns the fullURL set by setFullURLName, or if not set, returns the contents of the name field.

◆ getReadAsSoFile()

static SbBool SoWWWInline::getReadAsSoFile ( )

inlinestatic

Queries the ReadAsSoFile flag.

Definition at line 261 of file SoWWWInline.h.

◆ getTypeId()

virtual SoType SoWWWInline::getTypeId ( ) const

virtual

Returns the type identifier for this specific instance.

Reimplemented from SoNode.

◆ isURLDataHere()

SbBool SoWWWInline::isURLDataHere ( ) const

inline

Returns whether URL data is here (i.e. whether setChildData() has been called.)

Definition at line 206 of file SoWWWInline.h.

◆ isURLDataRequested()

SbBool SoWWWInline::isURLDataRequested ( ) const

inline

Returns whether URL data has been requested.

Definition at line 201 of file SoWWWInline.h.

◆ requestURLData()

void SoWWWInline::requestURLData ( )

inline

Requests that URL data be fetched.

This will invoke the application callback to actually fetch the data and can be called before the inline does this for itself (see setFetchURLCallBack()).

Definition at line 196 of file SoWWWInline.h.

◆ setBoundingBoxColor()

static void SoWWWInline::setBoundingBoxColor ( SbColor & c )

static

Specifies the color of bounding boxes displayed.

◆ setBoundingBoxVisibility()

static void SoWWWInline::setBoundingBoxVisibility ( BboxVisibility b )

static

Specifies when bounding boxes are displayed.

The bounding box can be rendered along with the children (ALWAYS), only until the child data is loaded (UNTIL_LOADED), or not at all (NEVER). Default is UNTIL_LOADED.

◆ setChildData()

void SoWWWInline::setChildData ( SoNode * urlData )

Sets the child data the inline should display.

The application should set child data after it has fetched data for an inline node.

◆ setFetchURLCallBack()

static void SoWWWInline::setFetchURLCallBack	(	SoWWWInlineFetchURLCB *	f,
		void *	userData
	)

static

Application callbacks invoked when the inline needs its URL data fetched.

This happens the first time the inline is rendered, or if it needs to compute a bounding box and the bboxSize field is not set, or when requestURLData() is called.

◆ setFullURLName()

void SoWWWInline::setFullURLName ( const SbString & url )

inline

If the name field contains a relative URL (e.g. "foo.wrl" instead of "http://bogus.com/foo.wrl"), the inline cannot resolve the URL reference.

This method allows the application to tell the anchor what its full URL should be. getFullURLName() returns the fullURL set here, or if not set, returns the contents of the name field.

Definition at line 178 of file SoWWWInline.h.

◆ setReadAsSoFile()

static void SoWWWInline::setReadAsSoFile ( SbBool onOff )

inlinestatic

Sets the ReadAsSoFile flag.

If TRUE, assume that "url" points to other Open Inventor files on local filesystem, and load them directly as if this were an SoFile node instead of using SoWWWInlineFetchURLCB.

Definition at line 257 of file SoWWWInline.h.

Member Data Documentation

◆ alternateRep

SoSFNode SoWWWInline::alternateRep

Specifies child data that can be used instead of fetching data from the URL.

On read, if this field is set and there is no fetch URL callback registered, the alternateRep will be used as the child data. Otherwise, it is the applications responsibility to set the child data (see setChildData()).

Definition at line 169 of file SoWWWInline.h.

◆ bboxCenter

SoSFVec3f SoWWWInline::bboxCenter

Defines the center of the bounding box surrounding the URL child data.

Definition at line 150 of file SoWWWInline.h.

◆ bboxSize

SoSFVec3f SoWWWInline::bboxSize

Defines the size of the bounding box surrounding the URL child data.

Definition at line 155 of file SoWWWInline.h.

◆ name

SoSFFilePathString SoWWWInline::name

Specifies the URL which the application should fetch as child data to this node (e.g. "http://bogus.com/homeWorld.wrl.gz").

Definition at line 161 of file SoWWWInline.h.
